Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 296.36 g/mol gives Amphotensid EH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Amphotensid EH (CAS 94441-92-6), molecular formula C14H27NO4Na and molecular weight 296.36 g/mol, is a CATO reference standard with documented purity and traceability.
Amphotensid EH (C14H27NO4Na) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
